This project brings together the offices of AP-HP (Assitance Publique-Hôpitaux de Paris), previously split in two locations in the French capital. On the grounds of Saint-Antoine Hospital, which can be considered a city within a city and counts 3,400 employees, the building provides workspaces, meeting rooms, and an auditorium. The building's triangular shape forms facades in three directions, where the different levels open outward with continuous balconies. The design of the facades begins with a serious architectural reading. A plant-covered perimetral concrete wall gives continuity with the garden.
